SXT LTE not reconnecting

Tue Aug 07, 2018 8:49 am

Hi All,

Has anyone had the below problems with the SXT LTE?
  • Can't automatically reconnect if connection is dropped.
    No traffic can passthrough the LTE connection then you have to disable the interface and enable it again. When this happens I can see the LTE interface got a IP address.
Currently I'm using a script to ping a specific IP address every 5 minutes. If it can't ping the IP address it disables the lte interface and enables it again.

Is there any other solution to this problem or is a script the only way?

We have the same problem. You do apply a soft reset but the LTE is not connecting until you do a hard reset the SXT LTE.

I have also been getting issues with the SXT LTE loosing connecetion and not reconnecting, I have tried scheduling a daily reboot at 4AM but this does not always return a connection.

There was a recent update available with a fix for the lte interface not working after reboot but when applied we loose connection all together and cannot get the unit to obtain an ip address from carrier (ee).

The only option was to downgrade back to 6.42.9 to get them to connect but they still need to be hard rebooted alot....

Yes I have the same problem as yours
I found this code but unfortunately it does not work on my model
:if ([/ping 8.8.8.8 count=10 size=64 interval=2s]=0) do={
	:log error "LTE DOWN";
	/interface disable <interface>
	/delay 1s
	/interface enable <interface>
} else={
	:log info "LTE FINE";
}

I've been talking to MikroTik support since September last year. I'm currently on v6.43.8 and I've also tested v6.42.11, but still experience the same problem.

Now they aren't responding to email.

It doesn't seem like they will fix this problem.

In my case lte1 is registered and has got IP address, but traceroute can't even reach nexthop.
Solved with watchdog to 8.8.8.8 for now.

Hi,
in my case this script works fine:

:if ([/ping 8.8.8.8 count=5 size=64 interval=2s]=0) do={
:interface lte set lte1 disabled=yes
:delay 5s
:interface lte set lte1 disabled=no
}

Facing the same issue myself. Have netwatch watching 1.1.1.1 then it cycles the LTE interface on down, I have seen issues where the netwatch script doesn't turn the interface back on (delay 1s not working all of the time)

I think the safest route is having a scheduled script, running every 2m, pinging an IP and on failure restarting the LTE interface

I have seen two ways to restart the interface

1) disable/enable the interface
2) reset the usb power

Has anyone seen a difference in both methods?

Still troubleshooting this. I have implemented a script to ping 1.1.1.1 and cycle the LTE interface when the ping fails.

My cell provider assigns my STX a private IP from there CGNAT pool. I extended my ping script to also ping that CGNAT private IP when 1.1.1.1 fails.

When the 1.1.1.1 ping fails, the ping to the CGNAT IP still works. I still have an assigned IP in the CGNAT pool but it cannot access the web (ping 1.1.1.1 fail)

So is the disconnect issue on my cell providers end? I was looking to see if there was an AT command(s) to tell the GCNAT/Network "Hey, reconnect my IP to WAN"

I wonder does other sim card modems just have firmware that cycles there internal interfaces under the hood when they lose connectivity?

If it is my cell provider disconnecting me and I still have an assigned IP from the CGNAT, then its understandable that the STX thinks all is well
